The object of the present invention to provide a solar cell sealing film, which has superior durability that maintains adhesive performance for a long duration under the circumstances of a high temperature and high humidity, exerts high crosslink rate at production of the solar cells, and suppresses occurrence of blister, and a solar cell using the sealing film. The solar cell sealing film includes: ethylene-polar monomer copolymer, an organic peroxide, and a silane-coupling agent, wherein the silane-coupling agent is represented by formula (I): in which R1 represents alkyl group having 1 to 3 carbon atoms, three R1s are the same as or different from each other, and “n” is an integer of 1 to 8; and the silane-coupling agent is contained in the range of 0.02 to 1.0 parts by weight based on 100 parts by weight of the ethylene-polar monomer copolymer.
